Abstract: Abstract The present invention provides novel curable organopolysi-loxane composition comprising at least about 50% by weight of a general organopolysiloxane having no more than two vinyl groups and up to about 50% by weight of a crosslink additive which is a polysiloxane having at least three vinyl groups and is copoly-marizable with the organopolysiloxane.  This curable composition when cured by heat, chemical or, preferably, radiation curing techniques produces crosslinked polysiloxane materials having unique combinations of cone penetration, elongation and tensile strength properties.  A preferred use for these materials is as a sealant.

Title: Method and apparatus for optical rf phase equalization
Inventor: BRANDSTETTER ROBERT W
IPC: G02F1/01
Filed: 1987-04-30
Granted: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE Phase equalization of a phase-distorted multifrequency signal is accomplished by acousto-optic modulating a coherent light beam with the signal taking the optical Fourier transform with the resultant Fourier plane containing all frequency components spatially distributed.  A control array, positioned in the Fourier plane and/or local oscillator, contains adjacent elements having their birefringence variable with respect to each other thereby selectively altering the light path length and/or amplitude of each frequency component passing through the element.  The resultant transformed image then undergoes optical down conversion to obtain the electrical signal having its phase equalized relative to the distorted input signal.

Title: Shortened tampon applicator
Inventor: SANDERS IRL R III
IPC: A61F13/26
Filed: 1987-06-26
Granted: 1991-08-20
Abstract: ABSTRACT OF THE DISCLOSURE      A shortened tampon applicator of the telescoping tube type employs an ejector tube to store a tampon it its distal end and an outer tube disposed by a slip fit thereover to thus shorten the overall length of the tampon and applicator assembly.          Directionally-locking inward flaps fixed within the distal end of said outer tube engage the distal end of the tampon stored in the ejector tube thus securing the latter relative to said outer tube while permitting only distal expulsion therefrom.  The ejector tube preferably has inwardly biased flexible portions at its distal end which serve to catch behind the proximal end of the tampon.  In the preferred version, the inwardly biased portions are unique undulations at the blunt distal end of the ejector tube which advantageously cooperatively functions with a tampon having an enlarged tail.

Abstract: HEADS-UP DISPLAY COMBINER UTILIZING A CHOLESTERIC LIOUID CRYSTAL ELEMENT                 ABSTRACT OF THE DISCLOSURE         A heads-up display (HUD) system employs a cholesteric liquid crystal combiner, an image source, and collimating optics to combine a generated image with an image in an observer's field of view.  The cholesteric liquid crystal combiner has a bandwidth, B, around a primary wavelength of maximum reflection, and the image source projects its images within bandwidth B for high efficiency of reflection.  Outside bandwidth B the cholesteric combiner has a high efficiency of trans-mission.  Images from the image source are projected upon the combiner which reflects the images toward the observer, together with images from the outside environ-ment in the line-of-sight of the observer.  Collimating optics are used to focus the projected images at a dis-tance away from the observer.

Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE       In a garment, such as briefs or diapers for incontinent patients, which employ hook-and loop fasteners, impairment of fastener operation by accumulation of lint on the hook-fastener tab is avoided by storing the hook-fastener tab in a pocket of the garment when the garment is being laundered. Preferably, the hook-fastener tab is secured in the pocket by elastic material so that it can be extended, stretching the elastic material, to fasten it to the corresponding female or loop-type fastener tab and will automatically be retracted into the pocket by the elastic material, as soon as it is released.  The pocket may comprise PVC or other semi-rigid pliable smooth material and may be fabricated together with the fastener tab separately from the garment and attached to it as a "retrofit".  Alternatively, it may be formed integrally with the garment.

Abstract: ABSTRACT OF THE DISCLOSURE          In  photoelectric  apparatus  such  as  a  pulse oximeter  for monitoring  a  parameter  of  the blood  in  a living  organism,  a  dark  current  correction  signal  is applied to the input at the preamplifier.  The correction signal is substantially equal in magnitude but opposite in sense  to  the photodetector output during dark intervals when the illumination means of the apparatus is disabled. Because  dark  current  correction  is  accomplished  at  the input of the preamplifier,  the preamplifier has substan-tially  increased  resistance  to  overloading  caused  by ambient light and hence may have higher gain.

A prefabricated bottom wall is secured between the opposed sidewalls of the tank and shell. The bottom wall is secured just above the temperature sensing and drain connectors of the storage tank with the top connections protected by a fiberglass covers.  A top shell cover includes an air foam insulation injection hole.  The bottom wall is a stable supporting body member having an outer sealing portion which is integrally formed with the body member or which is a separate element affixed to the body member to form an extension of the body member.  The outer sealing portion has sufficient compression or deflection to produce a seal in response to positioning the shell about the tank.  The insulation is introduced as a liquid which expands to form the insulation, with the bottom wall preventing the liquid insulation from passing downwardly of the dam.  The bottom wall is shown as a single piece styrofoam body member slightly smaller than the width of the cavity with an outer polyurethane seal element secured to the outer wall of the body member.  The styrofoam element or body member has radial slits to permit wrapping about the tank and has abutting ends, and is attached to the tank by an adhesive.
